The stress-strain relationship for paperboard loaded in edgewise compression relates to the strength of singlewall corrugated containers. This relationship can be approximated from the paperboard characteristics of stress measured at the maximum load and the initial modulus of elasticity. Based on typical characteristics for both linerboard and corrugating medium material a design matrix is constructed for a factorial analysis. Using a computer, various stress-strain relationships are paired together like they might be on the corrugator, and the theoretical effects of the stress-strain characteristics are investigated. Computer drawn design curves show how these linerboard and medium characteristics affect combined board edgewise compressive strength and box top-to-bottom compressive strength. The interaction between the stress-strain characteristics and paperboard thickness is used to suggest new criteria for evaluating paperboard. Author
